ATOMIZER.

Specification 01 Letters Patent.

Patented Jan. 19, 1909.

Application filed January 81, 1908. Serial No. 413,680.

To all whom it may concern:

Be it known that I, FRANK E. NELSON, citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Atomizers, of which the following is a specification.

My invention pertains to devices for comminuting hydrpcarbon and commingling the same with steam or other fluid under device for the purpose stated possessed of high capacity, and one which is simple and inexpensive in construction, is capable of being easily regulated, and is well adapted to withstand the usage to which such devices are ordinarily subjected and to be expeditiously and easily cleaned when necessity demands.

With the foregoing in mind, the nature of the invention and 1ts novelty and utility will be fully understood from the following description and claim when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a view, partly in longitudinal section and partly in elevation, of the device constituting the preferred practical embodiment of my invention. Fig. 2 is a side elevation of the perforated gland of the device, removed. Fig. 3 is a transverse section taken in the plane indicated by the line 33 of Fig. 1, looking in the direction indicated by arrow. Fig. 4 is a view showing in front end elevation a slightly modified embodiment of my invention, hereinafter referred to indetail.

Referring by letter to the said drawings, and more particularly to Figs. 1 to 3 thereof: A is the casing of my fiivel atomizingdevice, which is preferably of the form illustrated. The said casing is closed at its outer end by a plug a, and is provided at aboutthe point shown with a partition wall 6, and is also provided at one side of said partition wall with an orifice for the entrance of steam and at the opposite side thereof with an orifice d for the entrance of hydrocarbon. At its forward end, the casing A is provided with an eduction openin 6, preferably of circular form, while at a out the distance shown in rear of said openin it has three (more or less) interior projectlons f. It will also be noted by reference to Fig. 1 that the pres-' sure; and 1t has for its object to provlde a ries more or less grit and that the interior of the casing A is tapered or gradually reduced in diameter from the bases of the projections f to the openin 6, as indicated by g 'for a purpose presently set forth.

B is a needle movable rectilinearly in the casing A and having a handle portion h extending .rearward through the plpg a and. also having enlargements i on said handle portion and at opposite sides of the plug a, the purpose of which is to limit the movements of the needle in opposite directions. The portion of the needle in front of the handle portion h is tubular, isprovided at y with perforations, and terminates at its forward end in a tapered portion 70. At this point attention is directed to the fact that the needle B is guided in the partition wall I) and between the projections f of the casing A, and that back of its tapered end la the needle is of a size in cross-section to snugly occupy or fit inthe eduction opening 6 in the forward end of the said casing.

My invention contemplates the conduction of hydrocarbon through the tubular needle B and the conduction of fluid under ressure (preferably steam) through the orward portion of the casing A to the point where the hydrocarbon is atomized and the two commingled, and by reason of the construction just described it will be manifest that the steam in passing out through the opening e will after leaving the device contlnue in the direction it takes between the tapered wall 9 and the ta ered end 7; of the needle B, and consequent y will cut across theforward end of the needle and catch the hydrocarbon assing out said end and tear it into. monocu es, and at the same time. will effect a thorough mixture of air with the hydrocarbon. It will also be manifest that the projection of the needle B forward of the casing A precludes mixing of hydrocarbon and steam at any point inside the device, this being advantageous since it revents wear of the nose or forward end 0 the de' vice. This latter will be better appreciated when it is remembered that crude oil carfree the instant the hydrocarbon is commingled with steam, and that the liberated grit in passing through a restrictedopenmg like 6 would grindthe metal away and render frequent repairs necessary. It will further be manifest that the, volume of steam it is set at e may be regulated by moving the needle 7 B in the direction of its length and without recourse to the steam supply valve (not shown), and that the orifice aroundthe needle at the forward end of'the device may be expeditiously and easily cleaned.

It is essential that the hydrocarbon and steam be kept separated While in the device, and also that leakage of hydrocarbon at the rear end of the device he precluded. To these ends I provide glands G and D, stufling E between the partition wall I) and the gland D, and stufling F intermediate the two glands. The gland D is arranged opposite the hydrocarbon supply orifice d and around the perforated portion of the needle B, and

' in order to assure free passage of hydrocarbon into said needle, the gland is recessed exteriorly and interiorly as indicated by m and 71, respectively, and is provided with a plurality of perforations 72.

When a fiat horizontal flame is desirable I employ the modified construction shown in Fig. 4. This construction is similar to that shown in Figs. 1 and 8, with the exception that it has two opposite grooves M formed, by preference, in the casing A at opposite sides of the eduction orifice 6. By virtue of the provision of these grooves M, the two jets of steam meet and flatten out and in that way form a broad horizontal flame; the flatness of the flame being governed by the angle of the nozzle and the position of the needle relative to said nozzle.

The construction herein shown and described constitutes the best embodiment of my invention of which I am cognizant, but it is obvious that in the future practice of the invention such changes or modifications maybe made as fairly fall within the scope of my invention as defined in the claim appended.

Having described my invention, what I claim and desire to secure by Letters-Patent, IS I The herein described device comprising a carbon in its side at a pbint in rear of said steam inlet, a plug closing the rear end of the casing and having an opening, a hollow needle extending through said opening in the plug and having enlargements disposed at opposite sides thereof and also having a forward tapered end portion and a ortlon in rear of the tapered portion, of a dlameter to snugly occupy said eduction oplening and further having a plurality of sma apertures in its portion opposite the hydrocarbon inlet, a gland arranged in the casing opposite the hydrocarbon inlet and receiving said apertured portion of the needle and having an interiorly and exteriorly recessed and apertured portion arranged opposite the hydrocarbon inlet, a partition wall fixed in,

the casing in front of said gland, packin intermediate the forward end of said glan and partition wall, and packing arranged in the casing in rear of the gland.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

FRANK E. NELSON.
